JOURNAL-BOX.

Specification of Letters Patent.

Application filed June 12, 1914. Serial No. 844,651. 7

To all whom it may concern:

Be it known that we, JOSEPH BLOCKLEY BEADMAN and HARRY JOHNSON MAGKLIN,residing, respectively, at 2 West-View Terrace, Keighley, in the countyof York, England, and 49 Lightburn road, Ulverston, in the county ofLancaster, England, have invented new and useful Improvements inJournal-Boxes, of which the following is a specification.

This invention'relates to improvements in journal boxes, moreparticularly to the type used on railway rolling stock and the likevehicles, and wherein side chambers are provided for the reception ofthe lubricant in a liquid form. In this type placed beneath and incontact with the'journal whereby the lubricant is conveyed to the axle..Also, in this type of journal box provision is made for the receptionof the surplus oil when the "vehicle is in a tilted position and forsiphoning out any water that may have entered the axle box.

Heretofore great difficulty has been experienced in the eflicientlubrication of the journal owing to the difliculty of separating andremoving collected water from the oil. The water being heavier ingravity sinks to the bottom of the oil chamber and raises the level ofthe oil higher than some portion of the back of the axle box, therebyallowing the oil to'run out and be lost. In axle boxes provided with aseparate chamber at the bottom difficulty has been experienced inpreventing the outlet for the water to escape becoming clogged withdirt, and thus when the vehicle is tilted the water has become againmixed with the oil.

The object of this invention is to construct a railway or other vehicleaxle box with means for separating the water automatically from the oiland conducting it into a chamber provided with a suitable outlet throughwhich thewater can escape, and at the same time providing the separatingchamber with partitions that will prevent the water, as far as possible,becoming again mixed with the oil.

' The above named object is attained by arranging and constructing theaxle box as illustrated in the accompanying drawings, in which Figure 1is a sectional elevation of an axle box with the detachable cover fixedofjournal box the lubricant is usually raised by a pad thereto and witha water separating chamber attached thereto, and with holes com:mimicating with the space in which the shield slides, and also ticalpartitions and outlets in such shields; Fig. 2, asection on line A, B,Fig. 1; Fig. 3, a sectional elevation of axle tapering well and adivision between the shield guard slide forthe water to pass into thelatter and having vertical partitions formed therein; Fig.4, is asection on the irregular line C, D, Fig. 3; Fig. 5, is .an enlargedlower portion of Fig. 1; Fig. 6, is a sec: tional elevation on line E,F, Fig. 5;. Fig. 7, is a part plan of Fig. 5; Fig. 8,.a part sectionalview online G, H, Fig. 3. V

Like partsin all the views are marked with similar letters of reference.

a is a railway vehicle axle box of ordinary construction made of ironand steel, 6 the bottom of the same, c the: well or space for thereception of oil, and d the bush. 1 The axle box is provided with alubricating pad mounted upon springs. These last named parts are notshown in the drawings. e is the axle of the vehicle. The, axle boxesshown at Figs. 1 to 4 are provided with bulging sides f to form aninternal recess, or side chamber for the collection of any oil that willrun to the side of the axle box when fixed to an end tilting vehicle. gis the shield guide or groove, 7:, its cover, and zthe dust shield whichis. usually made of wood. All the above parts are of the usual andordinary I construction and will be readily understood without furtherdescription.

The water chamber 7' is formed either by fixing to the bottom of theaxle box a casting y' which is secured in position by means of setscrews 7a..(Figs. 2 and 6 or the water chamber may-be formedin the axleboxitself, as shown at Figs 3 andt, in which case a'tapering groove orchannel a is formed in the bottom of the axle box, and a communicationis formed between the shield. guide or groove 9 by, means of the hole 0.In the former case where, the water. chamber j'is Patented Mar. 9, 1915.

provided with verpart sectional elevation of ,the

formed in a separate casting two holes Z and m are in communicationchamber; the hole 7 end with the oil chamber 0, and atits oppositeend'with the-water chamber 7', while the with the water Z communicatingat one 6 as 1, Q,

narrower in width than compartments 1-:

partment 2. 5"by the vertical partitions p,

F water escapes 5 through the tapering hole r which, as shown exit holesr in 40' to be near bottom of the compartments 1 and 46 shown in dotted66 It will readily .frcm the Z or n and will rise in thecompartment 2ends of the hole we communicate respectively with the shield guide orgroove 9 and the water chamber. The lower portion: of the shield grooveg is thus made to form a 5 chamber for receiving the water that issepashield groove g and the water from the oil- 0 chamber first passesinto the water chamber j by gravity and enters the compartment 2 untilthe latter becomes full. WVhen the compartment 2 becomes full of water,the from the compartment 2 at Figs. 1 to 5 in the drawings, is arrangedjust below the dust SlllelCl i.

In some cases 1 and 3, as shown at Fig.8 of the drawings, the exit holesr in each case being arranged to taper outward so as to revent thembecoming clogged with dust.

-1, In this latter arrangement when the comeepartinent 2 becomes filledwith vertical partitions p and 9 form a kind of weir over which thewater can overflow intov compartments 1 and 3, and by arranging the eachof these compartments their bottom and the water readilv flows out oneach side thereof.

In some cases it may be found more convenient to place the exit holes r,r in the 8, as lines at 1, Fig. 8 instead of at the sides, as shown infull lines in the same view. Or, in other cases instead of employing ahole tapering outward a parallel hole may be employed having an inter-50 nal screw thread out thereon into which a short elbow pipe r isinserted, as shown in dotted lines at Fig. 8. The orifice of the outerend of the elbow pipe 1' may be either 7. parallel or arranged to taperoutward.

be understood that the means for separating the water from the oil iscontrollable by gravity alone. In the operation the water would collectin the shield groove 9 through which is passes oil chamber 0 througheither hole until it reaches the top of the vertical partition 79 and gwhen it would overflow into compartment 1 or 3 or both, and would after:

ward pass out through the exit hole or holes the lower portion of gwhich are itfmay be found more pref-' erable to arrange an exit hole ineach of the 30' compartments water the made to taper outward andtherefore-pro sent very little surface for the dust to lodge thereon.
